Want to show both the original (regular) and discounted (sale) prices in the WooCommerce cart? Use the woocommerce_cart_item_price filter to do this easily. Step 1: Go to your theme’s functions.php file. Step 2: Paste this code into the file:

// Show regular and sale prices in cart table
function modify_cart_item_price($product_price, $cart_item, $cart_item_key) {
    $product = $cart_item['data'];

    if ($product->is_on_sale()) {
        $regular_price = wc_price($product->get_regular_price());
        $sale_price = wc_price($product->get_price());

        $product_price = '<del>' . $regular_price . '</del> <ins>' . $sale_price . '</ins>';
    }

    return $product_price;
}
add_filter('woocommerce_cart_item_price', 'modify_cart_item_price', 10, 3);

Step 3: Save and upload the updated file. Now, your cart table will display the regular price as a strikethrough and the sale price as highlighted. This visual cue helps customers clearly see the savings. If you're using a custom cart template, some CSS or template adjustments may be needed.
